Abstract Emission and combustion parameters of common rail direct injection engine with different proportions exhaust gas recirculation (EGR) rate long-carbon-chain alcohol blends on performance are the main motive this research. To lessen dependency diesel fuel reduce harmful emissions, 1-hexanol is used, as it has better properties than small-carbon-chain alcohol, can be blended diesel. In engine, research was conducted, in which (1-hexanol-diesel) were variant, i.e., (10%, 20%, 30%) by volume whereas speed fixed at 1500 rpm varying load 25% step from 25 to 100%. Blends examined various rates (10 20%) see what impact they have properties. It observed that higher proportion 1-Hexanol, lower performance. The revealed for blend D70H30, around 8.24% rise brake specific consumption, slight hydrocarbon, 2.80% reduction thermal efficiency (BTE), 16.70% nitrogen oxides (NOx) emission. With 1-hexanol-diesel blends, noted function effortlessly, so a substitute upto 30% used while increasing total cost implementation. Increase hexanol EGR percentage shown negative efficiency, HC CO emission however, NOx CO2 emissions found decreased.
